    • Process for preparing bis(2-substituted ethylthiomethyl) ethers which comprises the steps of (1) reacting 2-hydroxyethyl mercaptan, or a 2-lower-alkoxyethyl mercaptan with a bis(aryloxymethyl) ether having the formula(ArOCH.sub.2).sub.2 Owherein Ar is a negatively substituted phenyl group, said reaction being carried out in the presence of an organic solvent and a strong base at a temperature of at least 60.degree. to about 150.degree.C. in an inert atmosphere and (2) extracting said bis(2-substituted ethylthiomethyl) ether. These compounds are useful intermediates in the preparation of bis(vinylsulfonylmethyl) ethers which are effective hardening agents for hardenable materials.
    • 制备双(2-取代的乙硫基甲基)醚的方法,其包括以下步骤:(1)使2-羟乙基硫醇或2-低级烷氧基乙基硫醇与具有式(ArOCH 2)2 O的双(芳氧基甲基)醚反应,其中Ar为 所述反应在有机溶剂和强碱的存在下,在惰性气氛中在至少60℃至约150℃的温度下进行,和(2)提取所述双(2- 取代的乙硫基甲基)醚。 这些化合物是制备双(乙烯基磺酰基甲基)醚的有用的中间体,它们是可硬化材料的有效硬化剂。
